Talk:Zero emission

Shouldn't it be "no harmful by-products"?

Shouldn't it be "no harmful by-products"? I mean, water is still an emission, and if you take an electric motor, that is literally zero emission - except that it does produce heat. I feel like this could be better explained. - IstvanWolf 05:33, 22 April 2006 (UTC)
 * I agree, I will try to rewrite it. Also, I added a small title section to your comment for future readability of the page. 137.205.192.27 21:14, 14 September 2006 (UTC)

Separating existing and future technology
I added some information on emissions associated with various forms of current electricity production and added a section for future technology ( such as fusion and CCS ). I suggest we keep the sections of currently widely deployed technologies separate from the ones in the research phase, as it makes it easier to compare the various technologies in an NPOV manner. I realise that the distinction is not always going to be perfectly clear, so some common sense will have to used (ominous phrase, I know). 137.205.192.27 21:12, 14 September 2006 (UTC)

Zero-emission propulsion
There should be made several subdivisions in this, one for each type of vehicle, notably:


 * Boats
 * Cars
 * Airplanes

Also, submarines, large ships (aircraft carriers, ...) can be described as they use different energy sources (nuclear propulsion). Finally the Ecologic rocket engine should be described, something which is possible trough the use of hydrogen, and hydrogen peroxide-rocket engines and Nuclear thermal rocket engines.

 * RD-0120 rocket engine by Energia-Buran described
 * Arcaspace's hydrogen peroxide-oxigen rocket engine described

Removing vegetable fuel and biofuel from zero-emission claim
Biofuel and vegetable fuels should be all removed, since they generate fumes and emissions. Whether or not this would generate 'no net emissions' is irrelevant (and also false, it still generates quite a huge amount of emissions).
 * How is it false? Don't you agree that the CO2 released when you burn vegetable oil first was taken out of the air by some plant?  And why would this be irrelevant?  If all fuel came from vegetable oil we would not increase the CO2 in the atmosphere.  Vincecate 14:37, 7 August 2007 (UTC)

Zero Carbon as environmental org supporting the zero-emission methodology
I think zero carbon now supports the zero emission methodology. Perhaps it could be mentioned in the article.

Zero emission transport and zero emission large scale energy production categories
Perhaps it is best to mark the articles with the technologies described with the "Zero emission transport" and "Zero emission large scale energy production" categories. Tell me what you think

Thanks,

re: climate change
Climate change as a result of greenhouse gasses is widely believed, but the degree is not known. Since there is no consensus among scientists as to the certainty that nor degree to which combustion engines contribute to climate change, I have added the phrase 'are believed to' to the first sentence in the 'Zero emission engines' section.

 * It is widely known and there is consensus among scientists to the certainty of increased man-made greenhouse gases intensifying the greenhouse effect that causes global climate changes. Of 19 (talk) 21:57, 4 July 2017 (UTC)
